20 Most Intense Video Game Moments Ever

19. No Russian - Call Of Duty: Modern Warfare 2

Speaking of out-of-nowhere scenes, Infinity Ward thought the best way to show you first-hand what the impact of terrorism on everyday life looks like, was to give you a gun and let you open fire in an airport.

Narratively it was set up as a way for character Joseph Allen to maintain his cover amongst a Russian gang; the titular "No Russian" referring to the lack of anyone speaking the language, because your fellow miscreants are also pinning this on America instead.

Controversial as all hell because you can join in the slaughter, the sheer visual impact of watching scores of innocent bystanders run for cover is horrifying in itself. Not to mention the personal realisation of your own voyeuristic limits, should you decide to pull the trigger.
